FITTING SUBMARINE SIGNALING APPARATUS TO VESSELS.

Specification of Letters Patent.

PatentedJune 27, 1911.

7 To all whom it may concern:

Be it known that I, THEODORUS S. BAILEY, a citizen of the United States, residing at Quincy, Massachusetts, and whose post-oflice address is care of Electric Boat Company, Quincy, Massachusetts, have invented certain new and useful Improvements in Fitting Submarine Signaling Apparatus to Vessels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to submarine signaling apparatus, and has been particularly designed for moving vessels such as submarine boats.

In order that the shadowing of the sound waves by the vessel may be reduced, and the area over which the signals are audible correspondingly increased, it is desirable that the sound-producing device of the signaling apparatus should be projected beyond the line of the hull ofthe vessel; andthis is particularly desirable in small vessels moving rapidly about harbors and coast lines. If, however, the sound-producing device is permanently projected beyond the line of the hull, it is exposed to injury by striking against docks, the hulls of other vessels,

and the like. In accordance with my invention, the sound-producing device is protected against such injuries by being housed in the hull of the vessel, and provision ismade whereby it may be projected beyond the line of the hull by projecting-mechanism operable from within the vessel. In this way the device may be housed, and protected from injury when not in use, and may be projected when a signal is to be sounded. Associated with the sound-producing device is a striker, adapted to impart sonorous vibrations thereto and operable from within the hull of the vessel when the device is projected.

The invention is also applicable to sta-' tionary vessels or signal stations, where it is desired that the sound waves should be propagated as widely as possible, rather than directed in one particular direction.

In the drawings I'have illustrated the in vention applied by way of example, 'to a submarine boat, and have shown the soundproducing device of a standard form, since the invention does not reside in that de-,

inder attached to the plating.

vice, but in the manner of mounting and housing it.

Figure 1 is an elevation, partly in section, of the stern of a submarine boat carrying a signaling-device mounted and housed in accordance with the invention; Fig. 2 shows a modification in the form of housing; and Fig. 3 is a section through the strikercontrol valve.

In Fig. l the housing a extends transversely of the hull of the boat, entirely through the hull, and is in the form of a cyl- Within the cylinder, and guided by it, is the signaling mechanism comprising a resonant body, which in this instance is a bell b, and a support or carrier in the form of a cylinder, 0, having the annular enlargement c, fitting into the cylinder (4. Attached to the inner end of the cylinder 0 is a projecting rod d, pivoted to the'end of a bell-crank lever e, journaled in this instance on the hull at 6, so that one arm 6 of the bell-crank projects within the vessel where it may be conveniently manipulated by a member of the crew. As will be readily understood, a movement of the lever arm 6 into the position shown in dotted lines, will project the bell beyond the hull of the vessel, and the return of lever arm 6 to the full-line position will retract it into the housing. Associated with the bell to impart sonorous vibrations thereto, is a striker which, in the particular instance illustrated, is a hammer f on the free end of a bell-crank lever f, the other arm of which is connected to a piston rod 9 extending from the piston g within the cylinder 0. The piston is moved in a direction to strike the bell by compressed air admitted through the flexible hose h, and is returned to the position shown in the drawing by the spring 71.

At Z, within the vessel, and preferably in proximity to the lever arm 6 is the control valve which, when in the position shown in Fig. 3, vents the cylinder 0 through the port Z, and which may be turned to connect the pipes m and m, on leading to the flexible hose hand we to the compressed air reservoir.

In the arrangement of Fig. 2, in which a signaling device of the same kind is shown, the housing 00 extends into but not through the hull of the vessel. The projecting rod d is replaced by a hollow rod d extending through a stuffing box in the end of the housing a. To the end of this hollow rod cl is connected a flexible hose h, which leads to the control valve. In this instance the lever e is mounted entirely within the vessel.

In either of the cases above described the sound-producing device is adequately housed, and may be readily projected and retracted; but the form of housing which extends through the vessel, as illustrated in Fig. 1, has certain advantages, because in that case the sound-producing device is well placed in deep water when projected, and yet it may easily be reached, or lifted out of the housing, from above, for purposes of repair.

What I claim is:

1. In a submarine signaling apparatus for vessels, at sound-producing device, a housing therefor in the hull of the vessel, and mechanism for projecting the sound-producing device from its housing beyond the line of the hull, and for retracting it within its housing, at will.

2. In a submarine signaling apparatus for ble from within the vessel for projecting the resonant body beyond the line of the hull and retracting it into its housing, and

a striker operable from within the vessel for imparting sonorous vibrations to the resonant body while it is projected beyond the line of the hull.

In testimony whereof I aflix my signature,

I in presence of two witnesses.
